Project E46 M3: Part 18 – Project M3 vs E90 M3 V8

By Pablo Mazlumian

We were pleased with our S54 3.2-liter in stock form, and the goal was to bring it up to V8 M3 performance. Was a 12% power improvement and 90-lb fat reduction enough? Find out inside! We test them to speed and in the quarter-mile. We also compare them from 30-100 MPH in third gear to compare low- and mid-range torque for you track guys! And why not--we even throw in a Mustang GT 5.0 in there...

10 Ways To Prepare Your Car For Spring And Summer

by Pablo Mazlumian

Most of us have a daily-driven vehicle that sees year-round driving. In an area where the temperature delta can exceed 100F in a given year, that starts to play a significant role in the vehicle’s wear and tear, as well as fuel economy. We’ve compiled 10 things to consider when readying your car for the upcoming warm season. Doing these things will not only ensure better fuel economy and overall performance, but increased life of the vehicle itself.

Project E46 M3: Part 17 – The preferred exhaust setup and more AEM tuning by MKC

by Pablo Mazlumian

Life would be a lot easier if we'd stayed with the stock headers, but when we tested our VAC headers in Part 3, the increase in power was too much to let go. Since then, we've tried different header-back systems but they either were too loud, droned at low RPM, or didn't fit all too well. Today, however, we think we've found something that works great and doesn't break the bank. Dynos graphs and video clips inside!

Subaru Clutch Forks Cracking Under Pressure?  Say It Isn’t So!

by Eric Hazen

Subarus have roamed the streets, tracks, and dirt for decades, with hundreds of thousands of upgrades available for nearly every aspect of these beloved cars.  Yet, one crucial part seemed to be passed over- the clutch fork! The clutch fork is Subaru’s Achilles heel. The clutch fork’s job is simple - disengage the clutch when you want to change gears. However, the stock part is prone to breakage and premature wearing of the pivot, especially when a performance clutch with higher clamping forces is used.

TESTED: Continental Tire ExtremeContact Sport

by Billy Johnson

“Same level dry performance as a Michelin Pilot Super Sport”. That is a HUGE statement by Continental when the PSS is hands down the segment leading benchmark.  Continental is extremely proud of their brand new ExtremeContact™ Sport tire that was just released earlier this month as a replacement for their ExtremeContact™ DW tire.  We logged nearly a thousand miles on the new Sport in both the wet and dry, and put it up against the outgoing DW in a back to back test at Palm Beach International Raceway to see if it lives up to Continental’s claims.

Project Viper GTS: Part 9 – RareFab/Roe Racing Oil Pan Baffle Kit

by Billy Johnson

Due to the high capabilities of the Viper, a huge strain is put on the factory oiling system on road courses and at the strip.  This can cause oil starvation and a spun rod bearing.  Using modern rubber can increase this risk, especially for 1996-1999 Gen-2 Vipers which have arguably the worst oil pan of any generation of Viper.  To combat this problem, we upgrade to the larger 10-quart oil pan and windage tray from the 2000-2002 Vipers and install RareFab/Roe Racing’s race-proven Oil Pan Baffle Kit.

Turbo Tech: Internal vs. External Wastegates

by Khiem Dinh

Every production street car comes with internally wastegated turbochargers. There are many reasons for this, but what is given up in torque and power compared to an external wastegate configuration which dumps the wastegate flow separately from the turbine exhaust flow? Luckily for us, Bren Tuning performed some testing on a 2015 Subaru WRX using exhaust manifolds from Killer B Motorsport configured for both internal and external wastegate configurations.

Diagnosing the Screech on a Silverado LB7 Diesel Engine

by Karla Pestotnik

Any car can eventually get a pesky squeak coming from the drive belt area under the hood. For many 1999-2007 General Motors V8s, this has become an infamous issue. However, this common issue is often more than just a belt change; it can be a little bit more complicated. In our case with the LB7 diesel Silverado, it was multiple sources contributing to some head-scratching pondering. Since this is the dedicated tow vehicle for the Karla Pestotnik Racing team and a big event is coming soon, we needed to get to work to diagnose and fix the tow rig.

AEM AQ1 - Using Data to Develop a Car

by Ramitha Edirisinghe

The goal of this series of write-ups is to show how powerful data logging can be for race teams, and how AEM’s line of data acquisition products gives access to this to the grassroots racer at an affordable price point. In the first section we went over the various features of the AEM AQ1 and what they meant. In this section, we’ll go over how the Jager Racing Team uses data acquisition to improve both Mark’s driving and the development of the car. In Section 3 we’ll go over lessons we learned while using the AEM AQ1, and how we installed the system on our car.

Building a NASA NP01 Prototype the Right Way with Stoptech! Part 3

by Mike Kojima

We have been following the Stoptech's team build of their NP01 in the MotoIQ Megashop for the past quarter. Although we stretched out the coverage for editorial scheduling, the actual build took about a month. Although the NP01 can be built relatively quickly as a multi-weekend project, we are showing the right way that Stoptech is going about it to build a first class, reliable NP01 that is going to win some races.

Tested! NOCO Genius Boost GB40-Emergency Jump Starter

by Mike Kojima

Having a dead battery really sucks. Not only can it leave you stranded, but you are also dependent on finding a good samaritan that is willing to give you a jump start. Not only is this bad because you are depending on luck, but it also exposes you to danger as you ask perfect strangers for help.

Project Mazdaspeed3: Building a Stock Class Cone Killer- Introduction and Installing Koni Shocks

by David Zipf

Autocrossing is a ton of fun. It’s super cheap, you can take almost any car under the sun, it’s fun, and the crowd is very friendly. Within 2 weeks of laying claim to a 2008 Mazdaspeed3, we were dodging cones. The Speed3 is a great Street Class car, with lots of grip, tons of torque, and low gearing to take advantage of that torquey, turbocharged Mazda MZR engine. In other words, a Mazdaspeed3 (or a Ford Focus ST, which is built on the same platform), makes for a great cone killer, with just a few simple modifications.

Making the Ford F-150 Ecoboost Drive and Tow Smoother with Eibach Shocks

by Rathyna Gomer

My dad's Ford F-150 Ecoboost is something I frequently drive, usually to pick up car parts and to tow one of the racecars out to the track. Similar to many folks who also own a racecar, the majority of my focus and money has gone into the racecar, not the tow rig. In actuality, I'm spending hundreds of more hours in the truck picking up parts for the car and towing the car to the track, than actually driving on the track.

Project 5.0 Mustang (The White One) Building the 302 Coyote Engine!

by Mike Kojima

We were eager to get into our motor and install the Ford Motorsports parts that would basically enable us to rev to over 8000 rpm reliably and breathe better on top. The parts we accumulated would bring us to a spec about the same as the Ford Motorsports Aluminator performance crate engine and a little bit more than the Drag Racing Cobra Jet NA engine.
